You must have enlisted the help of the great sound engineer Dr. Loof Lirpa. Did he use ultra high frequency sound waves to hyper vaporize the fuel? Dr. Lirpa usually brings out new products just in time to appear in the April issue of "Sound and Vision" magazine. I'm glad to see him branching out in to carburetors. It's been rumored for years that he had modified a Puch moped that is capable of speeds well beyond 100 mph while achieving almost 150 miles per gallon. Alan Henderson A13 Iowa

Be great...if it wasn't a 2 stroke carb. I've often wondered about a carb swap though, since the KLR650 uses the same carb bore size as my CRF450X. Also, having had one of those KLR style Keihin CV carbs on Suzuki before, I absolutely hated it. Worst carb I've ever had in my life. The Keihin FCR on the other hadn has been a great carb. Right now my 2009 KLR runs great, but if this carb ever has issues like the Suzuki did, I may entertain a carb swap. Ryan Phoenix, AZ Fred Hink wrote:

This Mikuni carb is used on all sorts of bikes. Two and four stroke. You should compare the constant velocity carb (like your Keihin CVK) to a direct pull carb like the Mikuni VM and you will see and feel the difference. Next time you are at a Harley rally let me know so I can watch you discuss that this carb is only for two strokes.

Hmmm, Interesting. I was under the belief that the single pull carbs weren't used on modern big bore 4 strokes because the vacuum can hold the carb open, hence the return/close pull of the second cable. My CR250 2 stroke has a carb similar to the single pull that's pictured. As for the Harley meet comment, you may be a while waiting for my answer, as I don't attend any Harley anythings. The dig on the Harley guys might be worth the trip, but I doubt I'd make it out without serious injury. But then again, maybe my theory is correct, since the classic Harley motor is by no means a "modern" engine. Ryan Phoenix, AZ Fred Hink wrote:

Back in the day (60s & 70s) when motorcycles were making lots more horsepower than they had brakes for, this may have been an issue on some bikes (2 & 4 stroke) Yes that was the original thought that big thumpers would develop lots of vacuum to stick open the slide, but I never heard of any bike sticking the carb open because of vacuum. It was more like sticking open because of a damaged throttle or cable or sucking in sand or dirt sticking the slide. A stuck throttle is never a good thing. Today's brakes are much better and as long as your throttle, cable and air filter are in good shape, there is minimal chance of a throttle sticking open. I think the twin throttle cable was first used when the EPA was cracking down on all sorts of things and this idea was just one of many. This Mikuni carb is The Performance Modification for Sportsters and other HD models using carbs. Since the Sportster also comes with a Keihin CVK, the Mikuni is a good fit for both the HD and the KLR. The reason you don't see larger carbs like the FCR and others is that there is not enough room because of the starter clearance to the float bowl. Accelerator pumps take up room and there just isn't any on the KLR. Also the Mikuni is about 1/5 the cost compared to the FCR. Most CR250s used a Keihin PE, PK or PW carb, which looks and operates similar to the Mikuni but are slightly larger.

Fred, is there a comparable dyno graph with the stock carburetor?

[James W. Flower]

Sorry, should have added that top speed is irrelevant to me but I like as much low end torque as I can get.

OK, here s a representation of the stock carburetor dyno run. _________________________________________ _____/ \ 0hp ______ / \32hp Fred http://www.arrowheadmotorsports.com From: James W.

The Mikuni direct pull carburetor has no vacuum lag and so you will feel more power down low sooner than on the stock carburetor. Fred http://www.arrowheadmotorsports.com From: James W.
